On the 13th August 1985 in so far as the story goes, 'Ron' Cook took a sound moderator to the lab' at Huntingdon, for Glynis Howard to examine. Prior to this DS Jones had collected it from Petsr Eaton on the previous day. How odd that neither DS Jones, nor DI Cook, and certainly not Glynis Howard, saw orade any mention of a pressence of any red paint in the knurl of the soynd moderators end cap?
